FLUID-FUEL BURNER AND SUPPLY iAPPARAT'U l Application filed October 25, 1922. Serial No. 596,783.

To all whom t may concern.'

Be it known that I, RoscoE V. JEFFER- SON, a citizen of the United States, and a vresident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in a Fluid-Fuel Burner and Supply Apparatus, of which the following is a specification.

My invention relates to a fluid fuel burner and supply apparatus, and has for its object to provide an apparatus for burning liquid fuel and also gas and to provide said apparatus with means for automatically feeding said fuel to the burner with the utmost degree of safety and efficiency.

A further object is to provide such an apparatus with means for fully distributing the fuel and for supplying an ample and properly distributed amount of air to the fuel and insure complete combustion thereof.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which, I l

The figure is a vertical sectional view showing the apparatus in connection with an ordinary type of furnace.

In the drawings I have shown my invention in connection with a furnace 5, the burner being mounted ink position upon the usual fire grate 6 thereof. Said burner may be readily adapted for use with any type of furnace or boiler.

My im roved burner, which is of the gravity supp y type, comprises an air distributing member 7 in the form of a vertical cy-1 linder provided at its lower end with an integral catch pan 8 and a seat 9 for reception of an air pipe ,or conduit 10 which ex tends to a suitable draft door, as the ash door 1,1, to which is preferably attached a chain 12 leading to a room above or which may be connected with an automatic control a paratus, said pipe may also be eX- tended3 through the furnace wall and provided with suitable draft control means if preferred. 'A fuel supply pipe 16 extends from the fuel supply mechanism, through air pipe 10, to a top plate or distributing plate 18 provided at the upper end of distributing member 7 of the burner. .Said

burner preferably also includes a deflecting cap 19 mounted over distributing plate 18, and baille plates 21, 22 and 23, suitable air outlets being provided around the air distributing member 7 of the burner, as shown. The supply apparatus provided with my burner comprises a fuel sup ly tank or reservoir 31 which is :mounte upon suitable standards 32' and communicates with Ythe supply or feed pipe 16 extending from the burner 7. A feed valve 33 is interposed in said feed ipe 16 for regulating the flow of fuel theret rough, and means is provided in the form of a chain 34 for controlling Said valve from the roof above or from an automatic heat regulator. A. supply pipe 35 leads into said reservoir from a sultable source of supply and is. provided with an -automatic control valve 36 actuated by a float 37 positioned in said reservoir, to maintain a constant head of fuel 38 in said reservoir, just a trifle higher, about one inch, than the upperface of the top plate 18, as indicated by the dot and dash line in the drawing, and weights 39 or similar'means are provided on the float beam 40 and have a cable 41 or similar means attached thereto for operating said weights from a distant point to regulate and determine the vertical vposition ofthe fioat. The pipe 35.is also provided with a positive cut-off valve 42.

An emergency tank l43 is provided and is preferably placed adjacent and below the reservoir 31, and an overflow pipe 44 leads from a distance (about one or two inches) above the usual head of fuel 38 in the reservoir to said tank, and an emergency or safety lvalve 45v is inter osed in the supply conduit l35, being control ed by a float 46 in said tank to shut ofll the supply from said conduit to the reservoir yin case the control valve 36 should stick or fail to function with an eX- cess of fuel in the reservoir. An overflow pipe 47 with a goose-neck 48 leads from the catch pan 8 to said emergency tank to prevent` any accidental overflow of said an and to shut off the supply b means of t e float 46 and valve 45, especial y in case the burner is not consuming fuel while the valves 33 and 36 are open.

It will be apparent from above disclosure that the fiow of fuel canI be accurately regulated by adjusting the control means 39 and 41 and that the fuel will then be automatically controlled b the float 37 and.'

valve 36 and can also e conveniently con-V trolled from a room vabove by means of a chain 34 and valve 33. It is also apparent that with the control valve 36, the emergency tank 4.3, and the safety valve 45, ample means is provided for automatically controlling the proper amount of fuel supply to the burner with the utmost degree of safety and efficiency.

While I have illust-rated and described the preferred form of construction for carrying my invention into effect, this is capa ble of variation and modification without departing from the spirit of the invention. I therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention,- what I claim as new and desire to secure by Letters Patent is:

1. An apparatus of the kind described comprising a fluid fuel burner arranged to be mounted on the grate of a furnace, a fuel reservoir, a valve controlled conduit connecting said reservoir with said burner, a supply conduit leading into said reservoir, a valve in said supply conduit controlled by a float in said reservoir, an emergency tank connected by an overflow conduit with said reservoir, a safety valve in said supply concontrolled conduit connecting said reservoir with said burner and extending through said air supply pipe, means for automatically controling said valve by the level of fuel in said reservoir, an emergency tank adjacent said reservoir, an overflow pipe leading from said reservoir to said tank,

an emergency valve in said supply pipe, and a float in said tank for controlling said emergency valve.

3. An apparatus of the kind described comprising a liquid fuel burner adapted to be mounted on the grate of a furnace, an air pipe mounted on said burner extending to the draft door of said furnace, a reservoir connected with said burner by a feed pipe extending through said air pipe, a valve in said feed pipe for controlling the flow of fuel therethrough, a supply pipe connecting said reservoir with a source of supply, a valve in said supply pipe, and means on said reservoir for controlling said valve, an emergency tank, an overflow pipe leading from said reservoir to said tank, an overflow conduit leading from said burner to said tank, and an einer ency valve in said supply pipe controlled y the fluid in said tank.

4. An apparatus of the kind described comprising a liquid fuel burner adapted to be mounted in the grate of a furnace, an air pipe on said burner extending to a draft door of said furnace, a reservoir connected with said burner by a feed pipe extending through said air pipe, `a control valve in said feed pipe, a supply pipe leading into said reservoir, a valve in said supply pipe, float means in said reservoir for controlling said valve, means on said float means for regulating its effectiveness, an emergencyv tank, an overflow pipe leading from said .reservoir to said emergency tank, an overflow pipe leadingl from said burner to said' emergency tank, a valve in said supply pipe,
